> Kids [...] face legitimate higher odds of crime or kidnapping. Because in the US they’re victims of gunshot, kidnapping, physical/sexual assault

This does not ring true at all.

Random kidnappings of children (i.e. by a stranger, not a parent, relative, or other acquaintance) are vanishingly rare in the US, to the extent that they typically make national news when they do occur. Random violence against children (again, by a stranger), even more so.

what kills and harms the most kids, criminals or cars?

where do you think kids are safest, in public where people look out for them or by themselves in a deserted area?

Nonsense. Crime has been continuously dropping since the 60s. What has changed is kids would rather spend time on their phones, online and playing video games.
